John and Don, Yes, the 3-hourly NARR-A datasets that can be retrieved through the NOMADS catalog link that Don posted were the ones that I loaded that caused the time aggregation issue. John: would you be a point of contact for a netCDF-Java fix for this issue or should I still cross-post this to the support-idv list? I hate to clutter email inboxes more than is necessary for this topic... anyway thanks for all the feedback on this!
